Description
- Model: DASO110
- ABB Part Number: 57120001
- Brand: ABB
- Series / Family: ABB Industrial Automation / Control Electronics
- Part Type: Electronic module
- Core Function: Application-specific interface and control electronics used within an ABB industrial automation system.
- Key Specs: Type designation DASO110; ABB identification number 57120001; designed as an equipment-specific replacement spare.
Product Introduction
A failed interface or control module can keep an older ABB automation system offline even when the main controller and field devices remain functional. The ABB DASO110 57120001 is an application-specific ABB electronic assembly intended for maintenance and replacement use in compatible industrial equipment.
When sourcing this type of legacy hardware, the complete identification is important. Both DASO110 and 57120001 should be included on the purchase request, while the markings and hardware configuration of the installed module should be checked before replacement (especially when several ABB boards are installed in the same cabinet).
Application Scenarios & Pain Points
Legacy ABB system maintenance requires careful component identification. When a DASO110 assembly develops a hardware fault, sourcing the exact 57120001 reference can avoid unnecessary replacement of an entire control section.
For industrial control cabinets, an application-specific electronic module can be kept as a maintenance spare when the associated equipment remains operationally important. Exact identification becomes especially important when multiple boards have similar housings or connector layouts.
At ambient temperatures above 50°C, technicians should pay close attention to ventilation, cabinet cooling, connector condition, and signs of thermal aging. Heat-related degradation can produce intermittent faults that are difficult to reproduce during a short inspection.
During planned maintenance, comparing the removed and replacement assemblies side by side can reveal differences in revision markings, connectors, mounting hardware, and board configuration before power is restored.

Common Error Codes & Diagnostic Symptoms
Symptom: Control section does not initialize correctly
→ Diagnosis: An internal electronic fault may prevent the DASO110 assembly from completing its normal startup sequence.
→ Action: Verify external power, wiring, and connected equipment, then replace the module if internal failure is confirmed.
Symptom: Intermittent loss of control or interface function
→ Diagnosis: Possible PCB-level component degradation, connector problems, or unstable internal circuitry.
→ Action: Inspect connections and operating conditions, then replace the 57120001 when the module is identified as the fault source.
Symptom: Repeated system faults after external checks pass
→ Diagnosis: If incoming power, wiring, and associated field equipment are operating normally, the electronic module may have an internal hardware problem.
→ Action: Install a verified replacement and perform complete system-level testing.
Note: No reliable manufacturer-specific numerical error-code table has been established for from the information available here. Host-equipment fault codes should be interpreted using the applicable ABB system documentation.
Cross-Reference & Lifecycle Migration
- Primary type designation:
- ABB identification number: 57120001
- Replacement reference: Use the complete identification when purchasing.
- Alternative part numbers: No alternative ABB number should be treated as a direct drop-in replacement without equipment-specific compatibility documentation.
- Revision compatibility: Confirm the hardware revision and connector configuration before substituting another version.
- Firmware: No verified firmware-flashing requirement is established specifically for this part number.
- Lifecycle position: Legacy / maintenance spare. The part should be managed as an equipment-specific spare where the installed ABB system remains in service.
- Buffer-stock strategy: For critical legacy equipment, keeping one tested replacement available can reduce downtime associated with long sourcing cycles.
Field Engineer’s Tech Notes
Warning 1 — Do not identify the board by appearance alone.
ABB legacy modules can have similar housings and connector arrangements. Check both and 57120001 before installation rather than relying on a photograph or physical similarity.
Warning 2 — Check the mating interface carefully.
Before fitting the replacement, inspect the connector pins, sockets, terminal connections, and mounting points. A damaged mating interface can produce symptoms that look like a defective module (particularly intermittent communication or control loss).
Strict QA & Testing SOP
- Part-number verification — Confirm the markings and 57120001.
- Label inspection — Record serial number, revision information, and manufacturer markings.
- Physical examination — Inspect the PCB, housing, connectors, terminals, mounting points, and visible components.
- Damage screening — Check for corrosion, contamination, cracked components, discoloration, and overheating.
- Connector inspection — Verify pin condition, socket alignment, keying, and mating surfaces.
- Electrical checks — Measure applicable power and continuity parameters according to the host equipment’s service documentation.
- Controlled functional test — Install the module in a compatible ABB test environment when an appropriate test setup is available.
- Operational verification — Check startup, control/interface response, alarms, and associated system functions.
- Extended observation — Monitor for intermittent faults, abnormal heating, or unstable operation.
- Final QA — Record test results and photographs before ESD-safe packaging and shipment.
Test videos are available upon request for units that undergo functional testing.
Buyer’s FAQ
Q: Can the ABB 57120001 be hot-swapped?
A: Do not assume hot-swapping is supported. Unless the applicable ABB equipment documentation specifically permits energized replacement, isolate power before removing or installing the module.
Q: What should I provide when requesting a quotation?
A: Provide both identification numbers: and 57120001. A photograph of the installed module label and connector side is also useful for confirming the required configuration.
Q: Can I use a different ABB DASO-series module as a substitute?
A: Not without compatibility verification. A similar type designation does not establish electrical, firmware, or system-level interchangeability.
Q: What warranty should I confirm before purchasing?
A: Ask the supplier to state the warranty period, unit condition, functional-test coverage, and replacement procedure in writing. Terms can vary significantly between new surplus, refurbished, repaired, and used units.
